Everytime I ADS, my sights flick unimaginably fast in another direction. Mouse sensor is fine, and in-game settings are normal as far as I can tell. Did the obvious (restarted Sandstorm/Steam/PC, unplugged mouse) to no avail.
Don't know what's causing it and it only does it in Sandstorm. Can't really play atm.
Any help is appreciated. Thanks.
